Kazoo - Japanese Counting

Counting in Japanese is one of the trickiest parts of the language — and most apps barely touch it. Kazoo is built entirely around helping you master it.

Start with the basics: learn how Japanese numbers work from 1 to 10, 100, 1,000 and beyond. Then dive into the real challenge — the dozens of counter words (助数詞) that Japanese uses for different types of objects, people, animals, days, and more.

Kazoo walks you through each counting category step by step: つ (tsu) — the general-purpose counter 日 (nichi/ka) — days and dates 匹 (hiki) — small animals 台 (dai) — machines and vehicles 人 (nin) — people 本 (hon) — long, thin objects …and many more Every category comes with built-in quizzes so you can test yourself as you go. Track your progress across all counters and see which ones you've nailed and which ones still need work.

Whether you're a complete beginner just learning to count to ten, or an intermediate student who keeps mixing up いっぴき and さんびき, Kazoo gives you the focused practice that textbooks and general language apps skip over.
